Hi everybody,
I didn't like having to run a resistor to slow my intake fans down, so I bought a couple of Enermax T.B. Silence 12s. Performance wise at 900RPM they are just right - Fractal Design Define R3 has restrictive intakes and it doesn't make sense to have high RPM monsters there. But after a while I noticed that a strange ticking-like noise is coming from my PC. I tried the good old "stop the fan with your fingers without having them cut off" trick and found that when both T.B. Silences are running I get the noise, but with just one running it goes away. I tried cleaning and lubricating the bearings and they no longer make noise when spinning the blades with my fingers, but when running under power the noise is still there. Do I have bad motors or is it just the way these fans are? I went through my fair share of fans and found that low-RPM fans tend to have louder motors.
